Being an iron sight diehard it was hard to do but the 336TS is wearing a scope. Of course with QR rings so the offending glass can be removed unless it's needed. Since I bought this several months ago with an XS setup, and I don't care for the XS sights, I sold them off and needed some suitable irons. That gave me another opportunity to experiment. I've settled on a Marble's orange fiber optic front bead and Williams WDOS barrel sight with their fiber optic ghost ring aperture slid into it. They aren't made to go together but they work well together. The aperture is designed for the WGRS receiver base but the dovetail mounting is the same as the WDOS. The glass is a cheap Deerhunter 2.5x20 with pretty generous eye relief. Enough so to allow mounting it way forward on the Leupold one piece base. I think it could be lowered a bit if I file off the base rails from the back cross groove rearward to make room for the eyebell. The shooters view of the iron sights is a little off center but you get the idea. Now I'm working on my Sierra 125HP/FN varmint loads to use on coyotes at deer camp after our spring Missouri turkey season is over.
